Definitions

  • the present invention relates to a conductor track for electronic purposes, in particular with a flexible conductor track made of a carrier foil with conductor tracks applied thereto, which are covered by at least one cover layer, for use in components.
  • the invention is concerned with printed circuit boards which are to be firmly connected to the component and have a high bending capacity and are used where an adaptation of the conductor track to the geometry of the place of use is desired.
  • Such strip conductors consist essentially of a flexible carrier film with a preformed cable set. The latter consists of individual conductor tracks, which are arranged electrically separated from each other. The track itself is electrically isolated.
  • an embodiment of the conductor track to the component and thus an orientation of the web in different directions is desired.
  • the track must be bent. The bending of the track must be done so that no injury to the web itself or the carrier or the cover, which can lead to a weak point on the conductor track.
  • high accuracy and positioning in the bending process and also in the attachment of the conductor to the component in question is desired. State of the art
  • EP 1 263 269 B1 discloses a film conductor with conductor tracks and a carrier film and a cover layer, the latter being provided with a hinge part which defines a defined bending line.
  • the bend line itself is formed by a groove-like recess in the hinge part. The production of such a film conductor is relatively expensive.
  • the invention is based on the object to provide a new way for the attachment and also the folding of flexible interconnects for electronic purposes, which is simple in their structure and in their handling and gives a very accurate definition of the mounting location and also the bending point.
  • the web is provided with over the edge of the conductor extending fasteners.
  • the fastening elements can be provided with plug-in buttons which can be clipped into corresponding openings of the component.
  • Other or additional mounting options for example using adhesive layers or even using ultrasound, are also possible.
  • the conductor track is provided at the respective folding position with a folding aid, which constitutes a folding edge at the folding point.
  • the folding aid is attached to one side or both sides on or on the conductor track.
  • an adhesive can be used and the folding aid glued to the track.
  • the folding aid In the case of attachment on both sides, it is favorable to form the folding aid in the form of a Velcro strip, so that the parts of the folding aid which project beyond the strip conductor edges are joined together like a velcro strip. Moreover, it is advantageous if the folding aid extends over the edge of the conductor track and at the same time can take over the function of a fastening element on a corresponding component in addition to the function as a folding aid. Conveniently, the use of a plug button in the folding aid, the plug button is outside the conductor and slightly resiliently presses the conductor to the relevant component.
  • the folding aids themselves are preferably formed from a nonwoven fabric, which is provided on at least one side with a pressure-sensitive adhesive.
  • the density of the nonwoven fabric should be at least 0.1 g / cm 3 .
  • the thickness of the folding aid is preferably selected in the range of 1 to 3 mm in order to achieve a favorable bending radius for the conductor track.
  • the minimum thickness should be 0.5 mm to form a clear bend radius.
  • the orientation of the folding aids to the bending edges on the conductor track can be supported with markings on the conductor track for positioning the folding aids.
  • Fig. 1 a to d a conductor track with a fastening element
  • Fig. 2 a to d a trace with fastener and folding aid

  • the marking 3 indicates the intended folding point 2 for the conductor 1.
  • the fastener 7 is made of a nonwoven fabric having sufficient rigidity to allow the folding operation.
  • the folding aid 4 also has the thickness D, which specifies the bending radius. In the example chosen, the thickness D is about 1 mm.
  • the edges of the folding aid 4 are slightly rounded, so that during the folding process no damage to the conductor 1 can occur.
  • the folding aid 4 is glued to the conductor 1.
  • the edge 5 of the folding aid 4 abuts the fold 2. Around this edge 5, the conductor 1 is bent, as shown in the view d. The conductor 1 is after its folding around the folding aid 4 in the attachment to the component not shown in detail covered by the head portion 12 of the plug button 9 and additionally held.
  • the individual parts are also reproduced in the views a to d.
